CENTRIFUGAL MACHENE.

SPECIFICATION forming part of Letters Patent No. 618,659, dated January31, 1899.

Application filed February 4,1898- Serial No. 669,125. (No model.)

To ctZZ whom it may concern:

Be it known that I, THOMAS C. GOOOH, a citizen of the United States ofAmerica, and a resident of Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements inCentrifugal Extractors, of which the following is a specification.

This invention, while relating to centrifugal extractors or separatorsgenerally, is directed more especially to improvements in or pertainingto the type of extractor or separator shown and described in LettersPatent No. 574,060, granted to me December29, 1896. In the said LettersPatent the conveyer through which the filtered or separated materialpasses away from the extractor is shown and described as located at thelower discharging throat or pipe, the latter revolving freely in theconveyer-flange. In operation the material is fed downward through theextractor and into the conveyer, and from thence to any desired point.

My present invention has for its object the provision of means by whichthe material which is fed into the base of the extractor is caused to becarried upwardly therein and to be discharged therefrom at a point nearthe top and afterward conveyed away. The construction by which thisresult is accomplished is fully described in the following detaileddescription, which is to be read in connection with the accompanyingdrawings, in which- Figure l is an elevation, partly in section, of anextractor embodying my invention. Fig. 2 is a top View. Fig. 3 is asectional view on line 3 3 of Fig. 1. Fig. 4 is a detail perspectiveview showing a portion of a rake-arm and the manner of mounting thering-plates.

Referring to the said drawings by letter, A denotes the extractor-drum,the lower conical end a of which is supported on beveled friction-disksI) Z), fixed to shafts Z) Z), journaled in bearings c c, and on saidshafts are pulleys 19 19 having belt connection with a source of powerby which the disks are rotated and the drum revolved. The upper'conicalend a of the drum is provided with a collar a which is engaged byguide-rollers (1 cl, rotatably mounted on the main frame of theextractor, whereby the position of the drum is main- The drum isopen-ended, and at its tained.

,lower end is an inwardly-extending flange a providing, with the wall ofthe drum, an annular receptacle d. The wall of the drum between the endsto a is perforated and lined with felt or other similar material throughwhich the separated liquid is filtered. Concentric with the drum is acasing E, having a lower trough-shaped end 6 to receive the liquid,which is carried off therefrom through a pipe 6.

F denotes a'rake composed of a number of arms f f, secured at theirinner ends to a Vertical rod f, which is slidably mounted at its ends inguides g g. In practice the rake moves from side to side of the drum,the means for imparting this motion consisting of pitmen h 7r,respectively connected to the rod ends and oppositely connected tocrankdisks 7L2 7L3, carried by a vertical shaft 7b, which is rotated,through the engagement of a worm gear-wheel h thereon, with a worm 7L0on one of the shafts l).

The material is fed to the drum through a pipe 1' and is depositedtherefrom into the receptacle a. The centrifugal action of therapidly-revolving drum causes the material to be carried against thewall of the drum and to be'separated from its liquid contents,which isfiltered through the lining and perforations and collected in thecasingtrough e, from which it is carried off, as previously stated. Thecentrifugal action to which the material is subjected has the furthereffect of carrying the material to the upper end of the drum, and to aidin securing this result the arms of the rake are provided with bevelededges which deflect the material upwardly, or, in other words, produce aresult similar to that effected bya screw conveyer. To confine thematerial to the conveyer-wall and also to prevent the escape of thematerial from the upper open end of the drum, I employ ring-plates jj,which are secured to the rake-arms and which provide, with thedrum-wall, an annular passage, through which the material is carried.These plates j, which are shown in vertical section in Fig. 1 andin'cross-section in Fig. 3, are cylindrical in form and secured to therake-arms by engaging grooves provided near the outer end of the latter.These plates form practically an unbroken surface and the inner wall ofthe annular passage.

The material is therefore through the employment of the means stated andalso through the centrifugal action of the revolving drum graduallycarried to the upper end of the drum and in its ascension is freed fromthe liquid contents. The separated material finds its way out of thedrum through apertures 7.: 7c, which are in register with the annularopening Z of a conveyer-casing L. This casing incloses the drum and issupported by the frame of the extractor, and for conven ience ofattachment it is constructed in two parts or sections connected togetherat ac. The material entering the casin g by the opening Z is carried bygravity to the dischargeoutlets Z, from which may lead conveying pipesor troughs, as will be understood.

My improved extractor is designed to remove the moisture from sugar anddistillers slops, the oil from cotton-seed, and other liquids from likesubstances.

The drum, in lieu of being vertically arranged, as shown, may be mountedto assume an angular position or may be horizontally arranged.

I claim as my invention 1. In a centrifugal extractor or separator,

the combination with a revoluble drum provided with apertures in theupper end, of a reciprocatory rake within the drum the arms of which areprovided with beveled edges, and a casing having an annular opening inregister with said apertures and having discharging-outlets,substantially as described.

2. In a centrifugal extractor or separator, the combination with arevoluble drum having a lower conical flanged end into which thematerial is delivered, and having apertures in its upper end, areciprocatory rake within the drum the arms of which have beveled edges,rings carried by the arms and providing with the drum-wall an annularpassage for the material, and a casing constructed in sections andprovided with an annular opening registering with the drum-apertures,and provided with discharging-outlets, substantially as described.

Signed by me, at Chicago, Illinois, this 17th day of January, 1898.
